I have two Pi 3B+. One is a few years old, the other brand new. I have an SD card (with a Volumio media player disk image on it) that boots fine in the old Pi. When I put it in the new Pi it won't boot. I get no output on the HDMI, and the green LED blinks in a sequence of 4 long, 7 short. The new Pi boots fine with a different SD card, containing a freshly downloaded Raspberry Pi OS. Does anyone have any ideas why an SD card would boot in one Pi, but not in another of the same model? And how to fix it?
